IMPROVEMENT I REGULATING CLASPS FOR 'ELASTiC TU-BES.

The Schedule referred to in these Letters Patent and making part ofthe same.

I, WILLIAM BUNGE, of the village of Oberlin, in the county of Lorain and State of Ohio, have invented certain Improvements in a Clasp or Valve for regulating the flow of duid through an elastic or iiexiible tube or pipe, of whichthe following is a specilicaion.

My invention consists in a clasp so formed4 that its application to a rubberv or any elasticl tube vor pipe will regulate the iiow of any fluid passing through the same; that is, by operating this clasp by the hand or otherwise, the iuid is permitted to How, but when not so acted upon it is self-acting upon the tube or pipe,

Aand stops the flow of the iluid `through the same. 4This clasp may be used for various; purposes, such as regulating the iiow of water through a hose-pipe when used for washing windows, carriages, sidewalks, buildings, sprinkling streets, watering gardens; also, upon the saine when used in extinguishing lires, and many other places where such a claspmay be used and isv desirable for regulating the flow of fluids through such a tube or pipe.

*,Descrpion of the Drawing; v l

Figure 1 is avsectional "iew of the clasp, when attached to the tube or pipe, showing the different parts of the same.

Figures 2 and 3 representa'side and end view,re spectively, of the/same.

General'Description.

A is the clasp, This clasp may be formed of wood, metal, or vulcanized rubber, and is made round, or oi' any convenient form, and of sulcient size to admit a halves; these halves are beveled Kor chamfered oi',v from the middle toward the ends, as at D Aand E, lig. 2, leaving a central fulcrum or pivot in the middle, as at F, fig. l; they are then placed with their internal surfaces together, surrounding the tube, and resting upon this pivot or fulcrum, as seen in fig. 1,'and are held together by a band, as at H, fig. 2, passing around the middle andl external surface of the clasp in the groove formed for its reception.

Around one end is placed an elastic band, as at G, gs. l and 2; this band forces this end of the halvesof the clasp close together upon the tube B, g. 1,-tbus closing this end tight upon the tube, and preventing the passage of any uid through the same, and at the same time, by means of the fulcrum F, opening the opposite ends of the clasp, bypassing these latv ter ends together with the hand or otherwise, as at c, iig. 1, theends surrounded by the elastic band Gare thrown open, permitting the immediate ow of the iiuid; by relaxing this pressure, the opposite-endsv of the clasp closes upon the tube or pipe, thus adjusting the flow of the Huid, as the pressure is relaxed or applied.

Having thus described my invention,

vWhat Ivclaim, and desire to secure by Letters Patent, is the followiug- Claim.

I claim- A hollow clasp, with'a central fulcrurn, in combination with an. elastic band, constructed and applied substantially as and for the purposes described andy set forth.
